How to Make a Chained List in Assembly?

I have a college job and need to do a linked list in assembly , I would like to know how to loop to insert all the elements in the list and keep them on . The list should contain the data of a broadcaster (name of the film, main actor, number of copies of the film ...)

This is the code I have made so far, it receives the user data and stores it in a placeholder (those .space are to reserve memory for each field), what I need is that after inserting the first record I can get save the position of the next ones (chain the registers).

.section .data

programtitle:       .asciz      "\n Gabriels Library\n\n" # 

asktitle:   .asciz  "\nWrite the title of the book"
askcategory:    .asciz  "\nWrite the category of the book"
askcharacter:   .asciz  "\nWrite the main character"
askyear:    .asciz  "\nWrite the year it was published"
askcopies:  .asciz  "\nWrite the number of copies the library has"

mostratitulo:   .asciz  "\nTitle: %s" # show the title
mostracategoria: .asciz "\nCategory %s" # show category
mostraator: .asciz  "\nCharacter %s" # show character
mostraano:  .asciz  "\nYear %d" #show year
mostracopias:   .asciz  "\nNum of copies: %d" #show number of copies

formstr:    .asciz  "%s"
formint:    .asciz  "%d"
formch: .asciz  "%c"
enter:  .asciz  "\n"

NULL:   .int 0

ttitulo:    .space 44
tano:   .space 4
tcopias: .space 4
tcategoria: .space 24
tator:  .space 44

prox:   .int NULL
naloc:  .int 124
